Objective To investigate the expressions of extracellular matrix metalloproteinase inducer molecule CD147 and epidermal growth factor receptor (EGFR) protein in gastric cancer and their relationship with the pathological behavior and prognosis.Methods Immunohistochemical staining was used to detect the expressions of CD147 and EGFR protein in 63 cases of gastric cancer and 40 cases of paracancerous normal tissues.The study was also combined with analysis of the pathological behavior and clinical follow-up survey of gastric cancer.Results The positive expression rates of CD147 and EGFR protein in gastric cancer were 77.8％ (49/63) and 42.9％ (27/63),respectively,which were higher than those in paracancerous normal tissues 25.0％ and 0 (x2 =27.851,P =0.000;x2 =23.233,P =0.000).In gastric cancer,the expressions of CD147 and EGFR were closely related to the depth invasion (x2 =5.992,P =0.014;x2 =13.148,P =0.000),TNM stages (.x2 =8.481,P=0.004;x2=14.589,P=0.000),lymph node metastasis (x2 =5.270,P=0.022;x2=20.261,P =0.000) and prognosis of patients (x2 =5.606,P =0.018;x2 =4.982,P =0.026).The expression of CD147 was also significantly correlated with Ki-67 expression (x2 =10.481,P =0.001).CD147 expression was positively correlated with EGFR expression(r =0.309,P =0.014).Conclusion The expressions of CD147 and EGFR are closely related to carcinogenesis,metastasis and survival time of gastric cancer.Detecting the expressions of CD147 and EGFR may be prognostic indicators of gastric cancer.

Objective To investigate the role of glucagon peptide-1(GLP-1) in blood pressure variability (BPV) in diabetic hypertensive patients. Methods A total of 120 diabetic hypertensive patients were included in this study. GLP-1 was used for the treatment. The values of body mass index (BMI), fasting blood glucose, glycosylated hemoglobin, creatine and 24-hour ambulatory blood pressure (BP) monitoring were detected before and after treatment with GLP-1 for six months. The clinical indices were compared before and after treatment. Results The values of fasting blood glucose (mmol/L:7.12± 0.64 vs 9.19±2.78), glycosylated hemoglobin (%:7.00±0.14 vs 8.28±1.32) and BMI (kg/m2:19.30±3.24 vs 24.5±4.53 ) were de-creased to the normal level after GLP-1 treatment for six months (P<0.05). There were significant decrease in the 24-h sys-tolic BP (mmHg:135.02 ± 16.57 vs 139.52 ± 15.60), daytime systolic BP (mmHg:132.5 ± 14.6 vs 136.44 ± 14.24), 24-h systolic BP variability (mmHg:12.20 ± 1.44 vs 12.73 ± 1.66), daytime systolic BP variability (mmHg:11.11 ± 1.48 vs 11.74 ± 1.52 ), and daytime diastolic BP variability (mmHg:7.03±1.42 vs 7.43±1.45) after GLP-1 treatment for six months (P<0.05). Conclu-sion GLP-1 can decrease BPV in diabetic hypertensive patients.

Objective To study the dynamic changes of transendothelial electrical resistance (TEER) on our in vitro model of brain blood barrier (BBB) made from primary culture of BALB/c mouse brain microvascular endothelial cells (BMVEC), and to explore the relation between TEER and BBB permeability, and search for the best culture condition. Methods BMVEC were isolated from BALB/c mouse and cultured on a transwell insert with special micro-pore. The cells were identified with immunohistochemical methods and electron microscope. TEER over BMVEC was measured after BBB model establishment for determining the 3H-Glucose permeability of BBB in vitro. Results BMVEC cultured in the transwell insert exhibited typical "flagstone" appearance and in a tight monolayer structure under electron microscope. Immunohistochemical detection of ZO-1 protein, a marker antigen of tight junction, showed smooth, continuous and tight junctions between confluent BMVEC. TEER over BMVEC monolayer increased to (346?10) ?/cm2 when the permeability for 3H-Glucose was decreased to the minimum. Conclusion BBB model in vitro made from primary culture of BMVEC in transwell has the basic characteristics of BBB in morphology, electrical resistance and permeability.

Objective To observe the effects of glucagon like peptide-1 (GLP-1) analogues liraglutide on expressions of nitric oxide synthase (NOS) and cyclo-oxygen-ase (COX)2 in renal medulla of type 2 diabetes rats, and the mechanism of its lowering blood pressure and promoting excretion of water and salt in kidney. Methods Type 2 diabetes model rats were generated by high-fat and high-sugar feeding for 8 weeks followed by intraperitoneal injection of streptozotocin (STZ). Subse?quently, eighteen type 2 diabetes rats were divided into two groups: liraglutide treatment group (DMT) and diabetes group (DM). Twelve normal rats were divided into two groups: liraglutide treatment wild type group (WTT) and wild type group (WT). DMT and WTT groups were given liraglutide (200μg/kg) by subcutaneous injection, DM and WT groups were given equivalent normal saline by the same way. The levels of blood glucose and blood pressure were detected at 0, 2, 4 and 6 weeks after treatment in groups of rats. Samples of urine were collected for detecting ion concentrations (K+, Na+and Cl-) af?ter treatment for six weeks. Rats were sacrificed and blood samples were collected for detecting ion concentrations (K+, Na+and Cl-). The expression levels of NOS and COX2 mRNA and protein in renal medulla were detected by real-time PCR and Western blot assay. Results After treating with liraglutide, the values of blood glucose (F=5.933, P<0.05) and blood pres?
sure (F=22.070, P<0.05) were gradually decreased in DMT group. After treatment with liraglutide for 6 weeks, the values of blood glucose (mmol/L:12.78 ± 3.82 vs. 18.75 ± 1.68) and blood pressure (mmHg:119.98 ± 4.43 vs. 136.42 ± 4.48) were signifi?cantly decreased (P<0.05) in DMT group than those of DM group (P<0.05). There were no significant differences in the concentrations of K+, Na+and Cl-between the two groups. There were higher levels of K+(mmol/L:46.55 ± 6.43 vs. 33.13 ± 9.71), Na+(mmol/L:56.33±8.83 vs. 41.20±7.25) and Cl-(mmol/L:159.81±25.06 vs. 71.44±12.99) in urine in DMT group than those of DM group (P<0.05). The mRNA levels and protein expressions of NOS and COX2 in renal medulla were significant?ly increased in DMT group than those of DM group (P<0.05). Conclusion GLP-1 analogues liraglutide may enhance the expression of COX2 by increasing the expression of NOS to excrete water and salt, and decrease blood pressure.

Objective To investigate the correlation between procalcitonin (PCT) and infarct related artery (IRA) spontaneous recanalization (SR) in patients with ST-segment elevation myocardial infarction (STEMI), and to investigate the value of PCT in predicting SR. Methods A retrospective study was conducted. A total of 263 STEMI patients who received emergency coronary angiography from January 2013 to April 2016 in cardiology department of Gansu Provincial Hospital were retrospectively included. Depending on the thrombolysis in myocardial infarction trial (TIMI) grade, the patients were divided into two groups, SR group (TIMI 2-3 grade) and non-SR group (NSR group, TIMI 0-1 grade). The baseline characteristics, serum PCT, high sensitivity C-reactive protein (hs-CRP) and biochemical makers before primary percutaneous coronary intervention (PCI) were compared. According to the value of PCT, the patients were divided into four quartile groups. SR rate of every groups were compared. Multiple logistic regression analysis was used to determine the independent predictor of SR. Receiver operating characteristic (ROC) curve was plotted to assess the diagnostic value of PCT for SR. Results In 263 STEMI patients, SR occurred in 77 patients and SR rate was 29.3%. There were no statistical differences in gender, age, body mass index (BMI), past medical history and IRA between the two groups, indicating that the baseline characteristics were matched. Compared with NSR group, utilization rate of the statins were significantly higher (35.1% vs. 22.6%, P < 0.05), the value of PCT, hs-CRP, uric acid (UA) in SR group were significantly lower [PCT (μg/L): 0.059±0.036 vs. 0.103±0.048, hs-CRP (mg/L): 3.07±4.13 vs. 5.93±7.80, UA (mmol/L): 321.4±77.4 vs. 354.2±114.1, all P < 0.05]. The quartile value of PCT were < 0.058, 0.058-0.078, 0.079-0.110, > 0.110 μg/L. SR rate were 48.5% (32/66), 29.9% (20/67), 26.9% (18/67) and 11.1% (7/63), respectively. SR rate of Quartile 1 was significantly higher than the other three groups (all P < 0.05). It was shown by multiple logistic regression analysis that PCT [odds ratio (OR) = 0.432, 95% confidence interval (95%CI) = 0.108-0.863, P = 0.016], hs-CRP (OR = 0.708, 95%CI = 0.516-0.905, P = 0.037) were independent predictors for SR. The area under the ROC curve (AUC) of PCT for predicting SR was greater than that of hs-CRP [0.784 (95%CI = 0.721-0.847) vs. 0.686 (95%CI = 0.619-0.753), P < 0.05]. When the cut-off value of PCT was 0.067 μg/L, the sensitivity was 81.6%, and the specificity was 66.7%. Conclusion PCT was independent predictor of SR, which has a power value in predicting IRA recanalization in patients with STEMI.
